Teckle is a tech mod that aims to add features from older mods that have since been abandoned, the first of which is item tubes a method of transporting items, if you ever used Redpower it's very similar to that. The mod is in active development and as such bugs are to be expected. Recipes are not currently listed on the wiki as they are subject to change, the mod does however have full support for JEI so install it to view recipes. You also need to install a mod that provides ores for all the recipes to function, I recommend Substratum or something like it.
Please report bugs here: https://github.com/elytra/Teckle/issues
